If it's still not working, try capturing traffic from the Dell switches with
Wireshark and then send traffic from the Cisco switch and also capture that.
Compare the frames and check that the salient parts line up - e.g. Ethertype.

I last played with Huawei routers about 10 years ago and it looked very much
like IOS. Interesting that they have changed.
Also interesting that you don't like Alcatel's TiMOS - I prefer it to IOS, and
find it comparable to Junos.
I suppose we all have our own tastes...

The ITU recommend the following levels:
5,6,7 = Customer
3,4 = Provider
1,2 = Operator
0= Local segment
I don't know if there are any rules of thumb for the CCM interval - faster is
more sensitive & unstable, slow is sluggish but stable. The spec allows between

RIP is useful as an edge protocol where there is a single access - less system
overhead than OSPF.
The service provider and the customer can redistribute the routes into whatever
routing protocol they use in their own networks.

It also scales better from the SP point of view. If you have 1000 L3VPN
services on your PE node using OSPF to the customer that would require a lot of
memory for the multiple LSDBs and a lot of CPU for the SPF calculations.
BGP is nicer but the reality is that many enterprises don't have the kno
For comissioning testing, you can use a hardware packet generator to send
packets to an Ethernet demarcation with a MAC-swap loopback, and analyse the
returned traffic.
For ongoing performance monitoring, having Y.1731 capable CPE is highly
desirable.

How smooth is the Ixchariot data stream? When Chariot was a NetIQ product it

The venerable mgen (http://cs.itd.nrl.navy.mil/work/mgen/) is another good
option, provided you don't want lots of bandwidth.
It has some flexibility in scripting the flows it creates.

The test plan you use depends upon what you want to test - raw pps throughput,
route convergence time, qos performance, etc.
We use Exfo (http://www.exfo.com) testers working to a mac-swap loopback for
commissioning testing of Ethernet access circuits, looking at the usual

Does anyone else despair at the CLIs produced by networking vendors?
Real routers use a CLI that is command based, like IOS, TiMOS or Junos. These

I have done QoS testing using Endace DAG cards - they can do capture as well as

In terms of FOSS routing platforms, I think Vyatta has a better user interface
than Mikrotik.
IMHO if the CLI is awkward then there a higher risk of misconfiguration.
I haven't used either enough to comment about stability.
